VALENCIA, Spain (AP): Mexican driver Sergio Perez is staying focused on his rookie Formula One season with Sauber despite a possible move to Ferrari.

Perez and Japanese teammate Kamui Kobayashi have unveiled the Swiss team's 2011 car at the Cheste Circuit in Valencia.

Perez remains part of Ferrari's young driver's academy but insists his present focus "is only Sauber. Obviously the dream is one day to drive for Ferrari ... my main job is in Sauber and Ferrari knows this very well."

Perez says the reaction from his move to F1 has been enormous in his native country, adding "the whole country has waited a long time, 30 years, since we had a Mexican in Formula One."

Perez's addition has also led to a number of Mexican sponsors for Sauber.
